Solution: The flat-rate EMI is calculated using the formula:
\[EMI = \frac{Loan Amount + Total Interest}{Number of Months}\]
Total interest calculation The total interest under the flat rate method is:
\[Total Interest = Loan Amount \times Rate of Interest \times Time (in years)\]
Here, the loan amount is 6,00,000, the rate of interest is 12% = 0.12, and the time is \(n\) years. So:
\[Total Interest = 6,00,000 \times 0.12 \times n = 72,000 \times n\]
EMI calculation The EMI formula becomes:
\[16,000 = \frac{6,00,000 + 72,000n}{12n}\]
Multiply through by 12n to eliminate the denominator:
\[16,000 \times 12n = 6,00,000 + 72,000n\]
\[1,92,000n = 6,00,000 + 72,000n\]
Simplify:
\[1,92,000n - 72,000n = 6,00,000\]
\[1,20,000n = 6,00,000\]
Solve for n:
\[n = \frac{6,00,000}{1,20,000} = 5\]
Final Answer: The value of n is:
\[5\]
